Abstract

A temperature measuring probe for measuring excess temperatures at the exhaust of an internal combustion engine is provided which incorporates an NTC resistor in a gas-tight metal housing. The housing is vacuum-tight, shock-proof, and vibration-proof (10 g RMS, 0 through 500 Hz) and the probe is suitable for temperature sensing up to about 700 DEG C. The probe is particularly suitable for use as a temperature monitor for turbo-chargers.

Temperaturmeßsonde.Temperature probe.

Die Erfindung betrifft eine Temperaturmeßsonde mit einem Heißleiter, insbesondere zum Messen von Übertemperaturen am Auspuff eines Verbrennungsmotors.The invention relates to a temperature measuring probe with a thermistor, in particular for measuring excess temperatures on the exhaust of an internal combustion engine.

Heißleiter sind allgemein bekannt. Unter Heißleitern versteht man temperaturabhängige Widerstände aus Halbleitermaterialien mit vergleichsweise großem negativen Temperaturkoeffizienten. Derartige Heißleiter werden auch NTC (Negative Temperature Coeffizient-)Widerstände genannt. Während man bei elektronischen Halbleiterbauelementen vorwiegend Silizium, Germanium oder III-V-Verbindungen in einkristalliner Form als Grundmaterialien verwendet, werden Heißleiter als Einzelbauelemente praktisch ausschließlieh aus polykristalliner Oxidkeramik gefertigt. Die zu Formteilen gepreßten und gesinterten Heißleiterkörper bringen gegenüber anderen Halbleitermaterialien erhebliche Vorteile mit sich. Sie bieten vor allem die Möglichkeit,, spezifischen Widerstand und Temperaturkoeffizienten in weiten Grenzen mit verhältnismäßig einfachen Mitteln variieren zu können.NTC thermistors are well known. Thermistors are temperature-dependent resistances made from semiconductor materials with a comparatively large negative temperature coefficient. Such thermistors are also NTC Called (Negative Temperature Coefficient) resistors. While with electronic semiconductor components mainly silicon, germanium or III-V compounds in monocrystalline form are used as basic materials NTC thermistors as individual components made practically exclusively from polycrystalline oxide ceramics. The too Compared to other semiconductor materials, molded and sintered thermistor bodies bring considerable benefits Advantages with itself. Above all, they offer the possibility of having specific resistance and temperature coefficients in to be able to vary wide limits with relatively simple means.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Temperaturfühler in einer vakuumdichten, schock- und schüttelfesten (10g RMS, 0 bis 5QOHz) Ausführung zu schaffen, der für Temperaturen bis ungefähr 7000C geeignet ist.The present invention has for its object to provide a temperature sensor in a vacuum-tight, shock and schüttelfesten (10g RMS, 0 to 5QOHz) embodiment which is suitable for temperatures up to about 700 0 C.

Diese Aufgabe wird erfindungsgemäß durch eine Temperaturmeßsonde mit den Merkmalen des Anspruchs 1 gelöst.According to the invention, this object is achieved by a temperature measuring probe solved with the features of claim 1.

Die Erfindung wird anhand eines bevorzugten Ausführungsbeispiels näher erläutert. The invention is explained in more detail using a preferred exemplary embodiment.

Die in der Figur schematisch im Schnitt dargestellte Temperaturmeßsonde besteht im wesentlichen aus dem Meßheißleiter 10. Der Meßheißleiter 10 ist in einem gestauchten Rohr 1 aus einer NiFe- oder NiFeCo-haltigen Einschmelzlegierung (Vacon) montiert, wobei das Rohr 1 unten mit einem eingesenkten Deckel 2 verschlossen ist. Nachdem der Heißleiter 10 in das Rohr (Hülle bzw. Hülse) 1 eingeschoben worden ist, wobei sein unteres Ende in die VertiefungThe temperature measuring probe shown schematically in section in the figure consists essentially of the measuring thermistor 10. The measuring thermistor 10 is compressed in a Tube 1 made of a NiFe or NiFeCo-containing melt-in alloy (Vacon) assembled, with tube 1 at the bottom with a recessed cover 2 is closed. After the thermistor 10 has been pushed into the tube (casing or sleeve) 1 with its lower end into the recess

3 des Deckels 2 einrastet, wird er von oben her mit einem schuhcremedeckelähnlichen Flansch 4, der ein zentrisches Loch aufweist, eingeklemmt, wobei dieser Flansch 4 innen an das Rohr 1 durch Punktschweißen angepunktet wird. Anschließend wird das Rohr 1 oben mit einer Keramikscheibe 5 verlötet. Diese trägt zwei aufgelötete Röhrchen 6, die aus dem gleichen Material wie das des Rohrs 1 bestehen. Durch diese Röhrchen 6 werden die Heißleiterzuleitungen geführt.3 of the cover 2 snaps into place, it is from above with a shoe cream cover-like flange 4, which has a centric Has hole, clamped, this flange 4 inside is spot welded to the pipe 1 by spot welding. The top of the tube 1 is then covered with a ceramic disk 5 soldered. This carries two soldered-on tubes 6, which are made of the same material as that of the tube 1. By these tubes 6 are routed to the thermistor leads.

Nach einem Evakuierungs- und Belüftungsprozeß werden schließlich Zuleitungen und Röhrchen 6 miteinander verlötet. Dies geschieht z.B. mittels eines Argon-Bogen- bzw. Lotring-Flamme-Verfahrene. Dieser Verfahrensschritt ist durch die Tatsache bedingt, daß der Heißleiter- 10 zwar weder mit Co bzw. Co2 in Berührung kommen darf, aber et-, was 0, zum Nachoxidieren benötigt. Der angestauchte Metallwulst 7 erlaubt eine leichte Montage der Temperatursonde mittels einer Überwurfmutter 8 am Auspuffkrümmer der Motore. Der mit dem Bezugszeichen 9 versehene Pfeil zeigt die Richtung der Auspuffgase an.After an evacuation and ventilation process, supply lines and tubes 6 are finally soldered to one another. This is done, for example, by means of an argon arc or solder ring flame method. This process step is due to the fact that the thermistor 10 may not come into contact with Co or Co 2 , but something, which 0, needs to be oxidized. The upset metal bead 7 allows easy installation of the temperature probe by means of a union nut 8 on the exhaust manifold of the engines. The arrow provided with the reference number 9 indicates the direction of the exhaust gases.
